LOOSE-WHEEL CONSTRUCTION.

Application filed March 10, 1922. Serial No. 542,622.

T 0 (ZZZ w from it may concern:

Be it known that I, Gnoneu- Times, a citizen of the United States, residing at lrlontville, in the county of Morris and State of New Jersey, have invented certain new and useful Improvements in Loose-Vilheel Constructions, of which the following is a specification,

This invention relates to free-wheel constructions and it has for its object to provide a free-wheel construction in which the bearing for the wheel, herein shown as a pulley, shall form a housing or,container for lubricant, such as grease, and as such shall possess certain advantages in the way of applicability in the place'of any existing free-wheel, facility of assembling with the shaft forming an axial support, ample ca pacity for lubricant, and, simplicity of con struction.

In the drawing,

Fig. 1 is a side elevation of the improved free-wheel construction;

Fig- 2' is a section on line 2-2, Fig. 1; and

Fig. 3is a section on line 8-3, Fig. 2.

Let a designate any shaft on which a freewheel, such as a pulley, would be mounted.

I A housing is secured on this shaft, according to my invention, which in the example illustrated is constructed as follows: There is a sleeve 7), which, exteriorly, at least, is

cylindrical, thus forming a journal. -Abutting the ends of this sleeve and held clamped thcreagainst are two disks or heads 0 which are penetrated by the shaft, the heads being here circular and penetrated centrally by shown to be screws 7 which extend parallel with the shaft and pass freely through one hub and are tapped into the other. 9 designates a setscrew which is tapped into one of the hubs and so secures the housing against rotation relatively to the. shaft. The

lubricant Z through an aperture m having a screw plug n. H

By forming the housing as herein set forth I obtain an ample container for lubri-- cant within the pulley journal and make it possible. to distribute the lubricant uniformly over the full width of the surfaces to be lubricated, as by t he'holes 2' and grooves it, Moreover, the device is readily applicable to any shaft in the place of an existing freewheel thereon, assembling being readily accomplished by first securing one head 0 on the shaft by means of set screw 6, then abutting against and centering the sleeve with respect to said head, then fitting the pulley overthe sleeve, and finally abutting the other head against the sleeve in the centered relation and driving home the screws f. Y

Having thus fully described my inven tion, what I claim new and desire to'secure by Letters. Patent is cured thereon including spaced heads pene trated by the shaft, a sleeve surii"ounding and spaced from the shaft and interposed between the heads and forming exteriorly a bearing and means, extending between the shaft and sleeve and connecting the heads,

for clamping the heads and sleeve together,

and a wheel journaled on said bearing, the housing being adapted to contain a lubricant and the sleeve having means to pass the lubricant therethrough to its bearing.

2-. In combination, a shaft, a housing secured thereon including spaced heads having inwardly projecting hubs penetrated by the shaft, means arranged in one hub for securing the corresponding head to the shaft, a sleeve surrounding and spaced from the shaft and hubs and interposed between the heads, and means, xtending between the shaft and sleeve. and connecting the hubs, for clamping the heads and sleeve together, and a wheel journaled on said bearing, the housing being adapted to contain a lubricant and the sleeve having means to pass the lubricant therethrough to its bearing.

3. In combination, a shaft, a housing secured thereon and including spaced heads penetrated by the shaft and a sleeve surrounding and spaced from the shaft and held between the heads, said heads projecting peripherally 'beyond the sleeve and having inside raised fillets snugly fitting around the sieeve ends and said fillets and the periphery of said sleeve together form 7 ing a peripheral bearing channel, and a Wheel journaled in said hearing channel, said housing being adapted to contain lubricant and the sleeve having means to pass the lubricant therethrough to said channel;

4. In combination, a shaft, a housing secured thereon and including spaced heads penetrated by the shaft and a cylindrical sleeve surrounding and spaced from the shaft and held between the heads, said heads having inward continuous fillets snugly fitting around the sleeve ends and forming with the exterior of the sleeve a peripheral hearing channel, and a Wheel journaled in said bearing channel, said housing being adapted to contain lubricant and the sleeve having means to pass the lubricant therethrough to the channel. 7

In testimony whereof I affix my signature.
